" My invention is applicable or adaptable totypewriting and computing machines gen-v erally, but I have here shown it applied to a I emington-W'ahl machine. This combination, consisting of a Wahl'computer-mount# edL as an attachment on a Remington No. 11.- typewriter, is extensively manufactured,

sold and used; and much ofthe mechanism shown in the drawings is identical with this i manufactured and marketed combination;

- The Remington Nokll typewriter has a stationary framework comprising a base part A1, corner posts 2 anditop plate 3 on which last are mounted a front static arycarriage rail 4 and a rear stationary carriage rail 5 between which ismounted a traveling y or rollers 7 In the carriage a paper roller 1,

or platen 8 is mounted and lprovided with 75 case shift mechanism, not shown, for shift-A ing it up and down. The carriage 6 is dra-wn across the machine toward the left by means of a spring drum `10, band 11 and hook or bracket 12, this last secured to the carriageand having the band` l1 connectedY therewith. T he step-bystcp feed of the can` y riage under the propulsion of the spring.

drum 10 is controlled by feed mechanism in'- cluding a'feel rack 13 mounted on the; rear ends of arms 14, which arms are pivoted'at. 15 to the 'carriage 6, and are pressed downward by springs 16 into engagement with a feed pinion l'vmounted onlthe forward end of a shaft having one or Ymore escape 'f ment "wheels `18 mounted on the rear end thereof. `Two escapement wheels areherev shownzand Vthey are controlledby a, dog20 mounted on a lever o r dog rocker 2l wlnch.

isconnected by a`link22, arms 23 and rock shaft24 with -a. universal bar` 25 lying beneath th'e printing luv levers 26` Said key levers-have printing keys 27 mounted on their forward ends and they have their rear ends pivoted, atV 28 in the base of theimachine, and they are provided with restoring or other adjustable push piece shaft 52 mounted in the base 1 of the ma- 'printing key springs 29. These printing key levers, through means of links 30, sub-levers 31 and .links 32, actuate front strike type bars 33 at 42 in a frame 43 secured to the base 1 and The lethe top plate 3 of the typewriter. vers 41 are operated by push rods 44 piv- `oted to the lower ends of said levers and having denominational tabulator keys 45 at their forward ends, said rods being slidably mounted in frame piece 46 and provided with returning springs 47. Each of said rods also has mounted thereon a collar 48 and all of said collars or push pieces are so located as to operate a universal bar 50 mounted on arms 51 which are rigidly secured to a rock chine. The arms 51 are connected by links 53 with arms 54 depending 'from a rock shaft 55 located in the rear part of the machine. Said rock shaft 55 also has a curved arm 56 mounted thereon and `connected by a link 57 with a carriage release lever 58 p which at its forward end lies beneath the feed rack 13, the construction being such that, when any of the keys 45 is operated, the lever 58 is rocked and raises the feed rack 13 out of the pinion 17, thus releasing the carriage from its escapement an leaving it free to run until it is arrested bythe operated one of the stops 40 intercejating one of the column stops 38. The said column stops can be made adjustable in various ways in order to provide for arresting the vcarriage at any desired letter space position. In the present instance there isprovidedI a full set of said stops 38, one stop for eacli letter space position, and said stops are slidably mounted on vthe bar'36, being ordinarily in a forward position on said bar such that they are'out of reach of the stops 40. Any one of said stops 38 can, however, tion by means of a setting lever 60 which is pivoted at 61 in a suitable support on the top late 3 and which is connected by means of a link 62 with a key lever 63, here shown as being similar in most-respects to the levers 26 and having a stop set key 64 vmounted on its forward end. The key lever 63 is'cut out at 65 to avoid operating the" universal bar 425. The lever 60 stands in suitable relation to the denomina- "tional stops 40 and such that when the carrollers 75, some of be slid backward to 'operative posicolumn stops 38 will be moved to operative position which is adapted to arrest the typewriter carriage in that letter space position when .the denominational stop 40, correspending to the decimal point, is operated. The stops 38 are restored to normal position by means which include a button 66 mount ed on thefrarne 43 and controlling a certain cam device which need not be here particulalrly described, being well -known in. the ar l The Wahl computer comprises an actuator 67 and a carriage`68 on which one or more totalizers can be adjustably mounted. These parts are here shown of Wahl construction. The actuator comprises a framework and some mechanism including a master Wheel 70, a rock shaft 71 having a series of graduated arms 72 thereon, and means, including a series of levers 73, for operating said arms 72.` The levers 73 are operated by links 74 connected with the key levers 26 of the numeral keys, which numeral keys are arrangedy in the back one of the four rows of printing keys.

The carriage 68 is supported and guided near the center of the machine by certain which appear in Fig. 1 and one of which appears in Fig. 3." These rollers are supported by a main frame piece 76 which also constitutes the main frame.

iece of the actuator 67 Said frame piece 76 is supported from the top plate of the typewriter by means of brackets 77 to which brackets said frame piece is secured by screws or bolts 78 and nuts 79.

The computer carriage 68 is connected with the typewriter carriage 6 by means of brackets or arms 80 secured to the type'- writer lcarriage by screws 81 and connected with the computer carriage through screws or bolts 82 threaded through the vertically disposed forward ends of the lbrackets 80 and secured in position by lock nuts 83. Each of the screws82 passes through a slot 84 in an arm 85 secured to and projecting from the corresponding end of the carriage 68.

The parts thus' far described are or may be vof substantially struction; and in fact, as far as my invention is' concerned, they may be of anysuitable construction, my invention not being limited in its application to this particular machine. S

I have shown one totalizer 86 which, with one or two exceptions that will be mentioned, is identical in construction with the ordinary Wahl totalizer. Registering mechanismincluded insaid totalizer is or may be identical with that used in the Wahl machine which includes a series of gears 87 adapted to be operated one at a time by the master wheel and also a series of numeral wheels 88, Fig. "2, gearedto said gears 87 the Remington-Wahl conand adaptedto show through suitable sight openings inthe casing ofthe4 totalizer,

Thel Wahl carriage 68'i`s`in the form of a bar of a'length to coverl the extent of carriage travel. Th'ecross section of said barincludes a `dove-'teilw and the side plates of `the` lVahl adding heads are made to fit 'this dove-tail in suchawaythat the adding head ior totalizer can beslid lengthwise of the carriage. The` adding head can b e secured in any letter space. positionv lengthwise ofthe carriage means of a latch or dey tent 91, Fig, 3, Aengaging the teeth of a rack bar 92 which isr secured to thefront face ofthe carriage '68,;thelateh` 91 beingdrawnv 'downward.4 intogengagement with the rack by meansA ofaispring To release the totalizerfrom its securingl means, said latch is lifted outof` engagement with `the rack by meansofa leverarm194 whichin,the Wahl machine, is situated lat the right-hand side of the' totalzer and has itsupper end bent off to form a sortof key.- `The latch 91 and the arm 94 are rigidly mounted on'a rock shaft 95pivotedat its end'sintheside platesof the totalizer. have'added tothe usual Vahl construction a .second Varm,96 at the left- :hand end of the rock;shaft.95 and have connected said two arms by `means of a yokevpiece. 97 extending substantially the width ofthe adding head." The `motion 'of the partsunder the impulse ofgthespring 93, is limited by means'of. across rod 98, Fig. 3.

`The purpose of the changes just above mentionedis'to enable-imc,- when a tabulator key is operated, to releasetheadding head from the`c0ntrol of 4its detent 91 so that said adding head isfree tomove.v lengthwise ofthe carriage 68.r AS1-will appear more fully hereinafter,:the'fadding -head moves toward the right-at the samextime'thatthe typewriter carriagel is moving' toward the left funderthe control of thev tabulator.

The release of' th'eadding head is effected by means of a lever arm 10U-having an antiriction roller 101 mountedonits free end in position toxcoperate withthe cross bar 97. '1`hi'sroller'101is von a `fore and aft aXis theframe I76"wlierre 'said frame supports thev rollers 7 To the 4rear ofthe-pivot 1021the and-fthe :lever arm isi pivoted at 102 on a transversehorizontal-pivot' mounted in ears 103f`bent upfrom abase104 of 'sheet metal secured by a screw 105 `tofthegtop part of lever `100 is 'formed witliavdependingarm 106 to which* is' Vconnected 'one fend f oi' fa spring 107, thev A'other"end 'of'V which `.-is'connected 'i ritiratransverse,rock shaft, :108. The free endfof the levei`-` ar1n` 106 lies behind a Lroller 110 mounted Ion' 'apinf 111 that connects two;

farms are-secured Vby? screws '1133vto `the rock toward thel rear, said arm beingT connecte by a link 117 with'an arm 118 xed on the transverse rock shaft' 52, which r ck shaft is rigidly connected with theuniversal bar 5,0 4of the tabulator'. The construction is such that when one of the tabulator keys' is operated, this bar 50 is moved toward the rear-and the arm 118, link 117 and arm A116 are drawn downward, rocking the shaft 108 and the arms 112 toward the rear, and thus rocking the arm 100, 106 and depressing the bar 97 andli'fting the latch 91 out of the rack 92, as shown in Fig. 3.v It will'thus be seen that the described mechanism releases thevlatch 91 yfrom the rack 92 when a tabulator key is operated. 1

" The adding head is moved toward'the i rightwhen lreleased as just described, by means of a` bar 120having its righthand end 121 bent downwardqand adaptedLOlie against the left-hand face of' the adding' the adding head when said adding head is in coperation with the master wheel. lThe H right-hand end ofthe bar 120 is formed yofV approximately rectangular cross section and itslefthand end 126'is formed smaller and round, and a spring 127 surrounds this part.

126 and is compressed between the eayr 124 and the shoulder formed at the lieginning of the rectangular part of, the bar. lThe tension of this spring is exerted to press the bar toward th'e right. he constructionjis such thatwhen a number is beingwritten inA an .adding column, the adding head .is se.- cured to the carriage 68 by means of the latch 91 and moves towardv the left with said carriage, forcing the barr120leftward with itv and Vcompressing the! spring 127. e

When. a tabulator key is operated, to move the typewriter-carriag into ayllfewfedding y zone,1the lever 100 releases thelatch 91'and thejspring }127moves,the. vbar 120 `and lthe adding head 86 toward the right until they are arrested by means -which will presently l be de scribed.- .Thef part 126 of thefbar l120 has atits-'left-hand end 'a nut 12S-to prevent theend of saidbar from'escaping fromfthe ear 124.1, The frame piece 123 is supported by two posts 130,` which posts project 'toward the front 'of the machine from a frameplatel 131 which in..tu`rn is secured to a'plate 132 I that extends acrossback of the actuator and is secured in position in any suitable manner. In the present instance this plate 132 lies between the mai'n frame piece 76 of the actuator, and the bracketsk 77, being secured in position at each end bythe bolt 78.

, shown each of the bars 'by Push from said bell cranks'behind the actuator I *order to'arrest the bar 120 and the ad ing head 86 1n harmony with the arrest of the typewriter carriage,lthat is to say, in

, a position of the same denomination as that of the-typewriter carriage, the bar. .120 is cut away at its rear face to form ashoulder 133, and this shoulder, as the barmoves toward the right, is' adapted to be arrested by any one of a series of denominational stops 134 consisting of the forward ends of push bars which are slidably mounted in suitable slots or holes 135 in the plate 123 and in similar apertures in the bar or plate 131,

said stops being situated a distance apart egual to a letter space interval of the carriage. The stops 134 are operatively connected with the denominational tabulator of the typewriter. Suchv connections can of course be made in variousways but as here rear end to a bell crank 136, a series of such bell cranks being pivoted on a rod 137, which rod is mounted in lugs or brackets' 138 projecting toward the rear from the frame plate 132. The bell cranks 136 are operated links 140 which pass downward and in front of the type bar basket and are pivoted vat their lower ends to the forward ends of bell cranks 141, which in turn are pivoted on the rock shaft 52 of the tabulator.

i The bell cranks 141 are 1/ connected by links denominational stop such that when this leyer is moved toward the rear of the machine by` 142 extending rearward therefrom above the key levers 26, and each of said links 142 has at its rear end a pin 143 that projectsftherefrom into a slot 144 formed in one of the levers 41. The construction is y the operati n ofthe corresponding key, it

first moves free of the linkL 142, due to the lost motion in the slot 144, and then operates the train of connections eX- tending up to the lstop 134, which stop is pushed toward the `front of the machine into contact with the bar 120 andinto the -path ofthe stop shoulder 133 on said bar. j

The bell cranks 141 pass forward through said link, and

f the series of links 30, which series extends across the front of the machine, each of said bell cranks being so located as to go between two of these links without interfering with said links.

In order to prevent overthrow of the adding head when it is moved toward the right bythe spring 127 and the bar 120, means may be provided for coupling said vadding khead with said bar.

adding head to one of the"cross bars.

v a tabulator key is operated, the

134-is pivoted at its of which To this end I have se- 1 cured a small hook 145, 'made of thin sheet metal, to head by means of a screw 146, this being one of the screws already employed in the Wahl machine for fastening the side plate of the As here constructed and as will be understood from Figs. 3 and 5, this hook forms a shallow knotch into whichthe depending end 121 of the bar l12() is adapted to engage. This bar may engage said hook permanently if desired but preferably it is capable of movthe left-hand side of the adding ing out of engagement with the hook as shown in Fig. 5. the bar 120 isV not exactly of rectangular cross section but on the contrary the angles of said `bar are slightly oblique so that in resting on tlle casing or guiding tube 122 the free end 121 of the bar is held by gravity, as shown in Fig. 5, in a position where it does not engage thishook 145. When, however, operated one of the stops 134 moving into engagement with the flat rear face of` the bar 120, rocks said bar into engagement with the hook, as shown in Fig. 3.

In operation the machine is vset for the particular piece of work in hand by setting to operative position suitable ones of the column stops 38, this being done in the machine shown by moving the typewriter carriage to the position in each adding column corresponding to the `decimal point and operating the stop-set key 64. If, for example., there are to be five numbers on a line, all

are to be registered on the totalizer '86, then five ofthese stops 38 will be set to operative position, and these may, for eX- ample, be the stops corresponding to the letter space positions 30, 40, 50, 60 and 70 of the typewriter scale; or they may be in other positions, depending upon the manner in which it is desired to arrange the num-v As shown in this ligurev sov izer will be moved to the right with said carriage. Matter other than said numbers can be written at the first part of the line if necessary, or for that matter, at any part of the line. yWhen he'is ready to begin the writing of ynumbers to be registered, the

releases the adding head from the bar 68 and moves it toward the left as fai' as it will go, which is to the position shown in Figs. 2 and 4. The-tabulator is then oper` operator, by manipulating the cross bar 97,

the described connections, releases the typewriter carriage from its escapement and also releases Vthe adding head 86 from its carriage' G8. The typewriter carriage'thenA runs to the left under the impulse Vrof the spring drum 10 until it is arrested by vthe, denominational lstops`f38 and 40, and the adding head moves toward the' right under the impulse of the spring 127 until it is 'ar-j rested by the shoulderl 133 and the, operated' one ofthe stops 134s If, for example, the first digit of the number to be added is of the hundreds denomination, then both thetypewriter -carriage and the adding head willbe arrested in thelhundreds position; that'is to say, in the positionfor writing hundreds on the typewriter and 'in the posi tion where the master wheel 7 O is in engagement with the hundreds gear 87. When the tabulator lrey'is released and the typewriter carriage'is restored Ito the control `of its escapement, the stop 4:0 is withdrawn out of the pathof the stopl 3S, the lever 100 rises allowing. the latch 91 to move intoy engagement withthe rack 92 and the stop 134 is withdrawn, leaving theadding head coupled to the computer carriage. :As the number is written and the typewriter and computer carriages are steppedtoward the left, they carrysthe adding head with them until the last,` digit of said number is written and reg isterechavhen said adding-head will be found A1n its normal or-initial position shown in 2 and l. 'The tabulator 1s then again operated, lu'nginglthe typewriter carriage to the proper denominational position in the second column and again moving the addingy r,head toward the right` to the same denomif national relation with vthe master wheel.

. llt-will `bejnotedthatwhen one of the' Ycolumn stops 3S has beenset to operativeposition, thesettingof this stop automatirally predetermines which one of the notches iu the rack 92 will be engaged by the detent 91.` InL'other words,` thesetting of one of Vthe .stops 38 predetermines-the exact posii ftylivriter carriage isv arrested by said.` stop `This position ou the ,c arriagejGS and tliisgnotch in the rack Y9i, will `be the same i'rhicl'iever one ofthe tabula'tor keys is operated. ln fthe present instance. only. tive ofsuch keys are shown connected up.
